So, when Jesus comes back and sets foot on the Mount of Olives , the Israeli immigration officials won't let him in?........but, seriously, the ancient 1st century Christians were having the same arguments, only in reverse. One group wanted the Gentile newbies to be converted to Judaism via circumcision first, then they were considered Christians. Paul effectively put that argument to rest. The whole Christian-Jewish argument is just as silly as the Middle Ages philosophical arguments over how many angels could dance on the head of a pin. It's an irrelevant and irresponsible waste of time talking about. A Jewish Christian is just as much Jewish as the Apostles were. Paul still considered himself Jewish, went to the synagogues and obeyed all the Law and practices of his ancestors. No one can point to any scripture that says if you become Christian you stop being a Jew. A Gentile is still a Gentile when he or she becomes a Christian. The essence of being a Jew or being a Christian is exactly the same. You are a Jew or a Christian in the heart, mind and spirit. There will be a lot of disappointed "Christians" at the Second Coming.........
Red your logic is flawed...the New Testament is way more than Paul’s letters...Jesus is the way the truth and the light...Paul never claimed that...however, when Paul’s eye’s were opened on the way to Damascus...he learned the Truth about Jesus, the Son of God...that was that we are all saved by Grace that believe in him...why would any Christian, who in fact does enter Heaven, question anything that our Lord has decided is welcome in his Kingdom...in fact for all Christians, we should pray that all accept his Word and enter the Kingdom of God!
